backs of some of the unfortunate birds, instead of decorating 

 the bonnets of women, who are responsible for the wanton 

 massacre of these pretty birds at their nests, as they are also 

 responsible for the sufferings and miserable death of the starv- 

 ing nestlings, deprived of the support of their parents ! 



Nest. This is described by Mr. Eagle Clarke as like that of 

 the Night-Heron, " composed entirely of sticks. The nests of 

 the Little Egret and the Squacco were seldom to be seen in

 ment of the latter." 



Eggs. From four to six in number ; and of a greenish-blue 

 colour. Axis, i"j-i'8$] diam., 1*3-1 '4.
